Relationship between long-term exposure to low-level arsenic in drinking water and the prevalence of abnormal blood pressure

► We focused on the impact of long-term exposure to low-level arsenic in drinking water on blood pressure, pulse pressure (PP) and arterial blood pressure (MAP). ► The prevalence of hypertension and abnormal pulse pressure (PP) and arterial blood pressure (MAP) is marked among a long-term and low-level arsenic exposure population. ► The prevalence of hypertension and abnormal pulse pressure (PP) as well as arterial blood pressure (MAP) significantly increases with the duration of arsenic exposure.
